With default settings, the slip coupling in the gearbox gives approx. 50% lower boat speed at idling for greatly improved manoeuvrability in close quarters or while fishing. The slip is controlled with the same lever as the engine speed.

During the first 15 degrees of lever movement, engine speed is at idling. Speed is increased by reducing the slip. When the lever is pushed further, the transmission is fully engaged and speed is increased from higher engine rpm.
